  2. 26. Factors influencing prognosis in acute coronary syndrome - A report from the SWEDEHEART registry

    Author : Oskar Angerås; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Acute coronary syndrome; acute myocardial infarction; risk factors; obesity paradox; socioeconomic status; cardiogenic shock; thrombus aspiration; SWEDEHEART; SCAAR; RIKS-HIA;

    Abstract : Background: Acute coronary syndrome (ACS) is one of the major causes of mortality in the world. The prognosis for patients with ACS is affected by several factors, such as baseline characteristics and treatment before, during and after hospitalisation. . READ MORE

  4. 27. Mode of delivery : does it affect contact with the newborn child, future reproduction and health-related quality of life five years after the birth of the first child?

    Author : Anna-Karin Klint Carlander; Karolinska Institutet; Karolinska Institutet; []
    Keywords : mode of delivery;

    Abstract : Background: Major changes have occurred in Swedish maternity care since the early 20th century and is now characterized by an increased medicalisation. The incidence of caesarean section and instrumental vaginal births has risen substantially in Sweden the last decades, which means that fewer women give birth spontaneously. READ MORE

  5. 28. Combining limnology and paleolimnology : a refined understanding of environmental sediment signal formation in a varved lake

    Author : Dominique Béatrice Maier; Christian Bigler; Sebastian Diehl; Jasmine E. Saros; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; varved lake sediments; diatom sediment signal formation; sequential sediment trap; seasonal process timing; ice thinning; varve compaction; climate impact; catchment properties; Earth Sciences with Specialization Environmental Analysis; geovetenskap med inriktning mot miljöanalys;

    Abstract : Paleoclimatic archives, such as lake sediments, extend our understanding of terrestrial and aquatic ecosystem dynamics in relation to climate variability beyond the period covered by instrumental data. In this context, annually laminated (i.e. READ MORE

  6. 29. Identification of viscoelastic materials and continuous-time stochastic systems

    Author : Magnus Mossberg; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; identification; viscoelastic; continuous-time; Signal processing; Signalbehandling; Signal Processing; Signalbehandling;

    Abstract : Two system identification problems, identification of viscoelastic material properties and identification of continuous-time stochastic systems, are considered in the thesis. The viscoelastic material properties are characterised by the frequency-dependent complex modulus. READ MORE

  7. 30. A short story of the long telomere : evidence in aging epidemiology

    Author : Yiqiang Zhan; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Telomeres are the sequences of nucleotides at the end of chromosomes. Each time a cell divides, telomeres become shorter. The length of telomeres can be replenished by an enzyme, telomerase. Telomere shortening is hypothesized as the biological origin of aging. READ MORE
